i had just finished my period cycle 2 days before this happend, we were in the middle of sex , and bright red thin blood came out, we stopped coz this had never happend before, i could tell it wasnt the same as period blood, i was so frightened, it wasnt painfull at all and we didnt do anything different than usual, it couldnt have been me getting split coz it would have happend our first time, but we have been sexxually active for over a year.
